Quick Start Set the Clock and Go

The thermostat is preprogrammed from the factory to operate one or two-stage equipment* without the need for further programming. To optimize the installation of this thermostat, follow the instructions in the Advanced Setup section.* The thermostat is not preprogrammed by the factory to operate electric heat or heat pump systems. To control these systems, follow the steps in the Advanced Setup section, on page 12.

Selecting the Heat or Cool Mode

Basic Operation

Selecting Your Desired Temperature (adjusting the setpoints)

AUTO OR PROGRAM MODE
Pressing the UP or DOWN buttons in Auto or Program mode will adjust both the heat and cool set temperatures simultaneously.

Programming a Daily Schedule

Press the MODE button. While holding MODE, press the UP button for two seconds to enter the time period programming.
NOTE: If the thermostat is configured for a single setpoint operation, there will be a prompt to enter only one setpoint.

About Advanced Features & Operation

• CALIBRATION – Under normal circumstances, it will not be necessary to adjust the calibration of the temperature. If calibration is required, please contact a trained HVAC technician to correctly perform the following procedure.
• DEADBAND OPERATION – Controls up to two Heat and two Cool stages (please see the diagram on the next page). The 1st Stage of heat or cool is turned on when:
•  The temperature spread from the setpoint is equal to or greater than the setpoint plus the 1st stage deadband (step #7, page 12). This 1st stage deadband is adjustable from 1-6 degrees and the default is two degrees.
• The 2nd Stage of heat or cool is turned on when:
• The 1st Stage has been on for a minimum of two minutes.
• The temperature spread from the setpoint is equal to or greater than the setpoint plus the 1st stage deadband (step #7, page 12), plus the 2nd stage deadband. This 2nd stage deadband is fixed at two degrees and is not adjustable.

About Advanced Features & Operation

The above figure assumes the minimum on time for the prior stage has been met to allow the next stage to turn on, once the headbands have been exceeded.

• ELECTRIC HEAT – Selecting Electric Heat (step #6, page 12), will cause the thermostat to turn on the fan immediately any time there is a heat demand. Since most gas furnaces control the fan, this feature should be off unless it is necessary for the thermostat to energize the fan with first-stage heat.
• EMERGENCY HEAT – Only available if you have a Heat Pump installed. To initiate the Emergency Heat feature, press the FAN button. While holding the FAN button press the UP button. The Cool setpoint display will read ‘EH’ (emergency heat).
• Operation – During Emergency Heat operation the thermostat will turn on the fan and the 2nd stage of heat when there is a demand for heat. Also during Emergency Heat, the 1st stage of heating or cooling will be unavailable.
• Exit Emergency Heat – Follow the same steps as entering Emergency Heat by pressing the FAN and UP buttons. During Emergency Heat, only OFF and HEAT modes are available by pressing the MODE button.
• FACTORY DEFAULTS – If, for any reason, you desire to return all the stored settings back to the factory default settings, follow the instructions below.
  WARNING: This will reset all Time periods and Advanced Programming to the default settings. Any information entered prior to this reset will be permanently lost.
• HEAT/COOL DIFFERENTIAL – The Heat and Cool setpoints will not be allowed to come any closer to each other than the value set in Advanced Setup step #8, on page 12. This minimum difference is enforced during Auto changeover and Program On operation.
  Note: To increase the spread between the heating and cooling setpoints, press the MODE button until only the heat setpoint is displayed; adjust to the desired setpoint. Press the MODE button until only the cool setpoint is displayed; adjust to the desired setpoint. Press the MODE button again to enter the Auto-changeover mode where both the heat and cool setpoints are displayed.
• MEMORY BACKUP – In the event of a power loss, the thermostat will retain
  the stored program settings without external power or batteries.
• SINGLE SETPOINT BEHAVIOR – When configured as a Single Setpoint thermostat, page 11, step 3, the large number is the setpoint. In Auto mode, the deadband is above and below the setpoint. To avoid short cycling in single setpoint it is recommended that the deadband be set for at least 2 degrees, page 12, step 7.
• KEYPAD LOCKOUT – To prevent unauthorized use of the thermostat, the front panel buttons may be disabled. To disable, or ‘lock’ the keypad, press and hold the MODE button. While holding the MODE button, press the UP and DOWN buttons together. The LOCKED icon will appear on the display, then release the buttons.
• To unlock the keypad, press and hold the MODE button. While holding the MODE button, press the UP and DOWN buttons together. The LOCKED icon will disappear from the display, then release the buttons.
